The frame body is used as an installation base, and the transmission components and other components of the linear module are arranged in the frame body. The dust removal module is configured to provide a seal for at least one side of the frame body, and the dust removal module is provided with a mounting position. The execution module is arranged on the mounting position and can move synchronously with the dust removal module, and the execution module is used to connect an actuator. The drive module is used to drive the dust removal module and the execution module to move synchronously along the frame body.

[0004] The above-mentioned linear module only has a single station and has greater friction during movement. Combined with the characteristics of existing linear motors, specifically, linear motors have many unique advantages over mechanical systems, such as very high speed and high acceleration, and are usually used for lightweight transportation. However, their high acceleration and high speed have the disadvantage of large wear, and usually they only have a single station. Therefore, we propose an independent double-station linear module. Summary of the Invention

[0006] To solve the above problems, the present invention provides an independent double-station linear module, comprising a base plate and a linear module body, wherein the linear module body is provided in two groups, and the two groups of linear module bodies are arranged in parallel on the surface of the base plate;

[0007] The linear module main body includes a linear module body and a movable slide. The linear module body is used to drive the movable slide to move along its length direction. Airflow plates are fixed on both sides of the movable slide by fasteners. A flow channel is provided on the airflow plate. When the airflow plate moves, a horizontal airflow is generated. The horizontal airflow passes through the flow channel vertically to generate lift on the airflow plate. The movable slide reduces friction with the linear module body through the lift.

[0008] In an optional embodiment, the linear module body further includes a stator, and a plurality of the stators are provided, and the plurality of stators are evenly distributed along the length direction of the linear module body; the stator is used to cooperate with the magnetic force of the mover in the mover slide to move the mover slide.

[0009] In an optional embodiment, a guide rail is provided at the edge of the linear module body, and the bottom of the mover slide is slidably connected to the guide rail.

[0010] In an optional embodiment, a protrusion is provided on the guide rail, and a guide portion is provided at the bottom of the movable slide, and a cavity is formed between the guide portions. The guide portion can move in the height direction of the linear module body and can move along the length direction of the guide rail.

[0011] In an optional embodiment, a protrusion is provided in the cavity, and the protrusion moves along the guide rail through a first ball structure.

[0012] In an optional embodiment, the guide portion contacts the side surface of the guide rail through a second ball structure.

[0013] In an optional embodiment, the flow channel includes a first airflow channel and a second airflow channel, and the first airflow channel and the second airflow channel are each provided with multiple groups, one opening of each of the multiple groups of the first airflow channels is provided on the first vertical surface of the airflow plate body, and the other openings of each of the multiple groups of the first airflow channels are provided on a side surface of the airflow plate body close to the bottom plate;

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present invention described herein can be practiced in an order other than that illustrated or described herein.

[0028] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical connections; direct connections or indirect connections via an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0029] Throughout this specification, references to the terms "embodiment," "one embodiment," and "an implementation" indicate that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or implementation are included in at least one embodiment or implementation of the present invention. In this specification, schematic representations of these terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or implementations.

[0030] like Figures 1 to 4 As shown, an embodiment of the present invention provides an independent double-station linear module, comprising a base plate 100 and a linear module body 200, wherein the linear module body 200 is provided in two groups, and the two groups of the linear module body 200 are arranged in parallel on the surface of the base plate 100;

[0031] By setting up two sets of linear module bodies 200, independent double-stations of the linear module are realized, and the requirements of specific application scenarios can be met according to actual needs.

[0032] Furthermore, the linear module body 200 includes a linear module body 210 and a movable slide 230. The linear module body 210 is used to drive the movable slide 230 to move along its length direction. The two sides of the movable slide 230 are fixed with air flow plates 240 by fasteners. A flow channel is provided on the air flow plate 240. When the air flow plate 240 moves, a horizontal airflow is generated. The horizontal airflow passes through the flow channel vertically to generate lift on the air flow plate 240. The movable slide 230 reduces the friction with the linear module body 210 through the lift.

[0033] Through the setting of the airflow plate 240, when the linear module body 210 drives the movable slide 230 to move linearly, the high acceleration characteristics of the linear module will generate high-speed airflow, and the airflow will be ejected vertically through the flow channel to apply lift to the airflow plate 240. The airflow plate 240 and the movable slide 230 are moved upward by the lift. In the process of continuously generating airflow, that is, in the process of high-speed movement of the movable slide 230, the friction between the movable slide 230 and the linear module body 210 can be reduced, thereby extending the service life of the linear module.

[0034] It should be noted that the linear module body 200 also includes a stator 220. Multiple stators 220 are provided, evenly distributed along the length of the linear module body 210. The stators 220 are configured to magnetically engage with the movers in the mover slide 230 to enable movement of the mover slide 230. Typically, when energized, the movers within the mover slide 230 generate a magnetic interaction with the stator 220, enabling movement of the mover slide 230 along the length of the linear module body 210.

[0035] Furthermore, a guide rail is provided at the edge of the linear module body 210 , and the bottom of the movable slide 230 is slidably connected to the guide rail.

[0036] The guide rail is provided with a protrusion, and a guide portion 232 is provided at the bottom of the movable slide 230. A cavity is formed between the guide portions 232. The guide portion 232 can move in the height direction of the linear module body 210 and can move along the length direction of the guide rail.

[0037] A protrusion 231 is provided in the cavity, and the protrusion 231 moves along the guide rail through a first ball structure 233 .

[0038] The guide portion 232 contacts the side surface of the guide rail through the second ball structure 234 .

[0039] The flow channel of the airflow plate 240 generates lift, which in turn causes the guide portion 232 to move along the side of the guide rail, thereby reducing the friction between the movable slide 230 and the linear module body 210. Furthermore, the second ball structure 234 and the first ball structure 233 enable the movable slide 230 to move along the guide rail more smoothly.

[0040] like Figures 5 to 7As shown, in this embodiment, the flow channel includes a first air flow channel 241 and a second air flow channel 242. The first air flow channel 241 and the second air flow channel 242 are each provided with multiple groups. One opening of each of the multiple groups of the first air flow channels 241 is provided on the first vertical surface of the air flow plate 240, and the other opening of each of the multiple groups of the first air flow channels 241 is provided on a side surface of the air flow plate 240 close to the bottom plate 100.

[0041] One opening of each of the plurality of second air flow channels 242 is disposed on the second vertical surface of the air flow plate 240 , and another opening of each of the plurality of second air flow channels 242 is disposed on a side surface of the air flow plate 240 close to the bottom plate 100 .

[0042] The specifications of each first airflow channel 241 and the second airflow channel 242 correspond one to one and are set in opposite directions, so that when the linear module moves, whether it moves to the left or to the right, lift can be generated through the flow channel, and the airflow plate 240 can be further moved upward to reduce friction.

[0043] The two openings of the first airflow channel 241 are respectively provided on the vertical surface and the bottom surface of the airflow plate 240, thereby converting horizontal airflow into vertical airflow. Similarly, the two openings of the second airflow channel 242 are respectively provided on the other vertical surface and the bottom surface of the airflow plate 240, thereby also converting horizontal airflow into vertical airflow.

[0044] Furthermore, each of the plurality of first airflow channels 241 and second airflow channels 242 has a horizontal section and a vertical section, and the horizontal section and the vertical section are transitioned by a smooth curved surface. The provision of the smooth curved surface reduces the loss of airflow velocity when the airflow passes through the horizontal section and enters the vertical section.

[0045] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
